Secure PDF to PNG

Export PDF pages as lossless PNG images with a transparent-safe white background.

Drop your PDF file here

or browse your device

A single PDF file, up to 100 MB. Files are processed on this device.

The most secure way to handle a confidential document is not to send it anywhere. This tool is built that way: your PDF file is read into the browser tab in front of you, processed there by your own device, and never transmitted.

That is a meaningfully different security model from "we encrypt uploads and delete files after an hour". Both are reasonable, but one requires you to trust a retention policy you cannot inspect, and the other removes the need to trust anything, because there is no server-side copy to protect in the first place.

You can verify this yourself. Open your browser's developer tools, switch to the network tab, and run the tool. You will see the page and its scripts load, and then nothing further — no request carrying your document to any server.

PNG is the format to reach for when a JPG will not do. It is lossless, so text edges stay crisp instead of picking up the soft halos that JPEG compression leaves around high-contrast lines, and it handles flat colour and line art far better than JPEG ever will.

This tool renders each page of your PDF as a PNG at the resolution you choose. It is the right choice for diagrams, charts, screenshots, documents with fine text, and anything that will be edited further after conversion.

How to convert a PDF file

  1. Add your PDF

    Drop in the document you want to export.

  2. Choose the resolution

    Screen at 72 dpi, High at 144 dpi, or Print at 288 dpi. PNG files are larger than JPGs at the same resolution.

  3. Convert

    Pages are rendered one at a time with progress shown throughout.

  4. Review the thumbnails

    Every page appears in the results so you can check them before downloading.

  5. Download

    Save individual pages, or download the whole set at once.

Why use this pdf to png tool

No upload at any point

Your document is read from your device into browser memory and processed there. It is never transmitted to any server.

Nothing is retained

There is no server-side copy to store, so there is no retention window, no deletion job and no backup holding your file.

Independently verifiable

Open your browser's network inspector and watch. No request carrying your file will appear, because none is made.

Lossless output

PNG compression discards nothing, so what you see is exactly what the renderer produced with no compression artefacts around text or lines.

Better for line art

Diagrams, charts and technical drawings keep clean edges instead of the softening JPEG applies to sharp transitions.

Safe to edit further

Because nothing is thrown away, a PNG can be cropped, annotated and re-saved repeatedly without degrading.

When people use this

Exporting a diagram

Technical drawings and charts keep their crisp lines in PNG, which JPEG compression would soften.

Preparing an image for editing

PNG is the better starting point when the page will be cropped, annotated or composited afterwards.

Adding a page to documentation

Documentation sites and wikis generally render PNG screenshots more cleanly than JPEGs.

Archiving page images

A lossless export preserves exactly what was rendered, which matters when the images are the record.

How to verify the security claim yourself

Security claims are worth exactly as much as your ability to check them, so here is how to check this one. Press F12 to open developer tools, or right-click the page and choose Inspect. Select the Network tab and clear whatever is listed.

Now add your file and run the tool. Watch the network tab throughout. You will see requests for the page's own JavaScript — including the PDF libraries, which are loaded on demand the first time you use a tool — and then nothing. No POST request, no upload, no transfer of your document. The processing happens entirely between your file and your device's memory.

You can go further and disconnect from the network entirely once the page has loaded. Every tool on this site except PDF to Word will continue to work perfectly with no connection at all, which is only possible because nothing is being sent anywhere.

The one deliberate exception is the PDF to Word converter, which needs server-side layout analysis. That tool says so plainly on its own page rather than being quietly grouped in with the rest.

How PDF to PNG works

Pages are rendered with pdf.js onto an HTML canvas at the scale you chose, where a scale of 1 equals the PDF's native 72 dpi. The canvas is pre-filled with white before rendering so that transparent regions produce white rather than black or undefined pixels.

The canvas is then encoded to PNG, which stores the pixel data losslessly. Each canvas is discarded immediately after encoding so that memory does not accumulate across a long document.

Privacy

Your files are not uploaded. When you add a PDF file, your browser reads it from your device into the memory of the tab you are looking at, and the pdf to png operation runs there using your own processor. Nothing is transmitted to any server at any point.

That means there is no file for anyone to store, no retention policy to trust, and no deletion schedule to take on faith. The document exists only in the memory of an open browser tab, and it is released the moment you close it, reload the page, or press start over.

The site uses standard anonymous analytics to count page views and how often each tool is used. Those events record which tool ran and whether it succeeded — never a file name, never file contents, and never anything that could identify a document or the person processing it.

No account is required, so no personal information is collected. There is no profile, no history and nothing tied to an identity, because no identity was ever created.

Security

The strongest security property this tool has is structural: your file never travels anywhere, so there is no transmission to intercept and no server-side copy to breach. This is not a policy that could change — it is a consequence of where the code runs.

You can verify it in about thirty seconds. Open your browser's developer tools with F12, select the Network tab, and use the tool. You will see the page's scripts load — including the PDF libraries, which are fetched on demand the first time a tool runs — and then nothing further. No request carrying your document is ever made.

For a stronger test, disconnect from the network once the page has loaded. The tool will keep working exactly as before, which is only possible because nothing is being sent.

Uploaded files are validated in the browser before anything runs: the extension must match what the tool accepts, the file must not be empty, and it must be within the size limit. Malformed documents produce a clear error and a retry option rather than a silent failure.

What this tool does not do

Being clear about limits is more useful than a feature list that quietly omits them. Output is always opaque with a white background, produced whole-page at a time, and text in the resulting images is no longer selectable.

If you need capabilities beyond that — redaction, PDF/A conformance, OCR, or scripted batch processing across thousands of documents — dedicated desktop software genuinely earns its licence fee, and this is not trying to replace it. For the specific job of producing a PNG images, everything you need is on this page.

Frequently asked questions

Are my files uploaded to a server?
No. The file is read into your browser's memory and processed by your own device. You can confirm this in your browser's network inspector — no request carrying your document is made.
How long are my files kept?
They are never stored anywhere to begin with. The file exists only in the memory of the browser tab, and it is released the moment you close the tab, reload the page, or press start over.
Can I convert a confidential document safely?
The processing model is designed for exactly that: the document never leaves your device, so there is no transmission to intercept and no server-side copy to be breached. As always, follow your own organisation's policy on handling sensitive material.
Should I choose PNG or JPG?
PNG for anything with text, line art, diagrams or flat colour, because it stays sharp. JPG for photographic content and whenever file size matters more than perfect edges. A page of body text will usually look noticeably better as a PNG.
Why are PNG files so much larger than JPGs?
PNG is lossless — it reproduces every pixel exactly, whereas JPEG achieves its small sizes by discarding detail the eye is unlikely to miss. For a page of text the difference can be several times the file size, in exchange for noticeably cleaner text.
Will the PNG have a transparent background?
No. Pages are rendered onto a white background so the output is consistent and predictable across viewers and editors.
Can I convert a specific page only?
The whole document is converted, but each page is listed separately so you can download just the ones you want. To convert a subset only, split the PDF first.
Is there a page limit?
There is no fixed limit, but every page is rendered and held as an image, so very long documents use a lot of memory. For documents over a few hundred pages, split first and convert in sections.
